Games dominate the top grossing and free Android app charts this week, with unsurprisingly prominent showings from Zynga, the now Zynga-owned OMGPOP and Rovio. Conversely, Android users willing to part with some cash for apps seem to be getting a little more productive this week with a variety of productivity, backup and device management apps making strong showings. Despite the launch of popular photo filtering/social networking app Instagram on Android this week, there’s no sign of it in the charts as yet — a surprise, given its popularity on iOS.

Zynga Poker — Zynga’s long-running Texas Hold’em game takes the top spot on the top grossing charts this week, with Dragonplay’s Live Holdem Poker Pro snapping at its heels from the No. 2 spot.

Temple Run — The immensely popular free 3D “run and dodge” game Temple Run from Imangi Studios has finally made the jump from iOS to Android.

The Sims FreePlay — Despite its parent publisher being voted “the worst company in America” by The Consumerist readers, the free-to-play real-time Sims title continues to prove popular and profitable, with a No. 9 showing in the top grossing charts.

Scramble With Friends Free — Zynga’s immensely popular asynchronous social game series continues to prove a steady moneymaker for the company, with the free version of the Boggle-like Scramble With Friends showing up at No. 14 in the top grossing charts.

This week’s top free Android apps

Draw Something Free — OMGPOP’s Pictionary-like game is still proving enormously popular, but has been dethroned from the top of the Google Play charts by Rovio’s latest and Temple Run, now sitting in the No. 3 position. The recent Twitter-based controversy surrounding OMGPOP’s takeover by Zynga does not appear to have harmed the game’s success to a significant degree.

Tiki Kart 3D — The free kart-racing game from Arb Studios takes the No. 19 spot on the free apps chart this week. The Mario Kart-esque game monetizes through in-app purchases of new vehicles, tracks and other virtual items, and is also ad-supported. It has seen over 5 million installs.

Advanced Task Killer — ReChild’s memory management app shows up at No. 24 on the free apps list this week. The app makes it easy for users to shut down unnecessary background apps to clean memory and save battery life, and has been installed more than 10 million times to date.

Cut The Rope — Physics puzzler Cut The Rope from Zeptolab takes the No. 4 spot on the paid app charts this week, with its sequel Cut The Rope: Experiments coming up behind it in No. 5. The game was updated on March 30, but this appears to have been nothing more than a bug fix release.
